This is a minimal demo project to show the capabilities of a Text2SQL system using `LangChain`, it contains all the things you required to build a basic RAG system. Using Chinook as the sample database.

## Before Start

First, make a copy of `.env.sample` and rename it to `.env`, and change any fields that need to be changed

Then:

1. Download `Chinook Database` from [here](https://database.guide/2-sample-databases-sqlite/).

   1. Change the connection string in the `.env` file.

2. Setup the `Ollama` for the document tokenization and interaction

   1. See [Setup - OllamaEmbeddings](https://python.langchain.com/docs/integrations/text_embedding/ollama/)

   2. See [Ollama](https://ollama.com/)

3. Get your LangSmith API Key from [here](https://smith.langchain.com/hub).

## Start the demo

Run `python main.py` and type anything you want to ask the RAG system
